Description
(1) technical field:
The utility model relates to a kind of monitoring device, especially a kind of monitoring device that can be triggered by the state parameter of testee.
(2) background technology:
In engineering practice, very important Practical significance is arranged for the record and the judgement of equipment operation parameters.For example the running temperature of main equipment is too high, can badly influence production safety; Perhaps operational outfit has a certain parameter to exceed standard in an of short duration time, finds and note the essential condition that this situation often is exactly the remover apparatus fault timely.This just needs the equipment that a cover can monitor in real time and write down.In order to address this problem, " Xi'an University of Technology's journal " discloses " design of Substation Insulator contamination on-line monitoring system " in the second phase in 2002, its main points are: adopt long-term method of monitoring insulator contamination leakage current in service in real time to come the pollution level of monitoring substation insulator.When insulator contamination is excessive, can in time write down and report to the police.System is made up of sensor, signal conversion unit, signal processing unit, D/A conversion unit, industrial computer, parameter set unit, real-time display unit and alarm.This monitoring system is carried out real time on-line monitoring to the Substation Insulator filth all the time and data is recorded in the industrial computer.In addition, " southern agricultural machinery " discloses " application of temperature real-time monitoring system in agricultural greenhouse " in the second phase in 2003, and this temperature real-time monitoring system is made up of temperature sensor, intelligent temperature detector, temperature monitoring management system and dialer.Real-time monitoring system is monitored in real time to variation of temperature in the agricultural greenhouse, and writes down the data of temperature variation with PC.
But the continuous running of real-time monitoring device and record can make the loss of monitoring device hardware too fast, and need to consume the more energy and a large amount of storage spaces, and equipment price and operating cost are higher.
(3) summary of the invention:
Equipment loss is fast in the prior art, the memory device demand is big in order to overcome, equip price and the high deficiency of operating cost, the utility model provides a kind of trigger-type monitoring device, this device is in holding state at ordinary times, when designated parameters occurs, can start and carry out data recording and warning; After disappearing, parameter recovers holding state.The utility model long service life, the memory device demand is little, and little power consumption is with low cost.
The utility model is made up of sensor, transmitter, direct current amplifier, data-signal switch, control circuit, false triggering chronotron, singlechip microprocessor, microcontroller power supply switch, power supply, alarm and recording unit.Wherein: the output of sensor is connected respectively to data-signal switch and control circuit after by transmitter and direct current amplifier.The control circuit output signal connects data-signal switch and microcontroller power supply switch by the false triggering chronotron, in order to the break-make of control data signal switch and microcontroller power supply switch.Power supply connects the microcontroller power supply switch.Data-signal switch and microcontroller power supply switch all are connected to singlechip microprocessor.Singlechip microprocessor connects alarm and recording unit.
During the utility model work, sensor is reflected as the variation of voltage with the variation of survey parameter, and outputs to data-signal switch and control circuit after the rectification amplification through transmitter and direct current amplifier, and the trigger voltage value that sets with control circuit compares.If the magnitude of voltage of sensor signal is less than trigger voltage value, control circuit is output as low level, otherwise is output as high level.When the output of control circuit is continuously low level, then the false triggering chronotron is output as low level, can not connect data-signal switch and microcontroller power supply switch, and device still is in holding state.Perhaps the output of control circuit is initially low level, reverts to low level again by the low height that changes afterwards in less than the time expand of false triggering chronotron, and then the false triggering chronotron is thought that it disturbs, still output low level.If control circuit continues the output high level and greater than time expand of chronotron, then the false triggering chronotron is exported high level, data-signal switch and microcontroller power supply switch connection, singlechip microprocessor is started working and data-signal is sent into recording unit, drives alarm equipment alarm simultaneously.
As a preferred version of the present utility model, described data-signal switch is selected CMOS type noncontacting switch integrated circuit for use.
As second preferred version of the present utility model, described microcontroller power supply switch is selected CMOS type noncontacting switch integrated circuit for use.
As the 3rd preferred version of the present utility model, described control circuit adopts a potentiometer, is used to be provided with trigger voltage value, and an end of potentiometer connects direct current amplifier and false triggering chronotron, other end ground connection.
As the 4th preferred version of the present utility model, described singlechip microprocessor adopts the CY7C68013 single-chip microcomputer.
As the 5th preferred version of the present utility model, described recording unit adopts USB electronic disk.
The utility model can be triggered by the designated state parameter of testee, and energy resource consumption is few when the utility model is in holding state; Because designated parameter is device record not when not occurring, required capacity of memory device is less, and is with low cost; And the utility model does not need long-time continuous firing, and the hardware loss is little, and serviceable life is longer.
